Tires filling tires with foam

[levsmith]

hey i have read alot about flat resistant tires and the nomorflats and i was just wondering if anyone has tried filling their tires with a foam to make it kind of like the nomorflats but it would fill the entire empty space in the tire to keep the tire from moving back and forth like they do with the nomorflats? i was thinking about doing something like that for the 4" wide chopper tire since they dont have nomorflats in that size. if anyone has tried this successfully could you tell me what kind of foam you used. thanks.

Good question, I'd like to know also.

I've seen lots of foam-in-a-can types, but I'm not sure if one would fill the tire and keep it hard, but I've thought about it, and may want to try it.

I also wonder if you could stack 3 or 4 of the foam no-flat foam bike tubes side-by-side that would fit your wheel's outer diameter to fill in the extra-wide tire....................

hey thanks for the reply. i've also seen the foam in a can stuff but i dont think it would get hard enough. i thought about putting more than one of the foam tubes in but i think it would be hard to get them lined up right and i dont think it would fill enough space to keep the tire from coming off the rim.

I have dealt with foam filled tires (monofoam) Only on low speed machinery tires. only drawback is it adds like a ton of weight & wont hold up to hi speeds. Not to mention you need at least a 4+ ply sidewall to keep tire from blowing apart when foam cures.. Stick to the air tires..

I know that the "handyfoam" sold in home improvement stores cures to a very hard consistency. It would crack and crumble under the load of a bicycle.

I've been doing some research on flat free tires. NO, you can not fill them yourself is what almost all say!
I had a friend blow a front tire yesterday on a pedal bike doing about 20mph he says. Broken leg, broken arm, and lots of road rash! Sucks to be him today!
So I just bought "Flat Free tires" from https://www.airfreetires.com I got 2
26 x 1.9 Kik Tire Sierra Unidirectional (559) - Premium HD Foam filled tires for $95.85 including S/H. That use to seem like allot for 2 tires until yesterday!
I'll post some updates after I get them, and try them out on the road.

if that stuff held up to long-term use, it would have replaced air in tires a long time ago

Air Is superior for shock absorbing ability.I had a friend who was very poor and he would take rags and cut them In large squares and pack them really tight Into his dual suspension rims.He said they were a pain to get on the rim and pack In the tire tight.But,They worked well once he got em on. He did not have a m.b. though and I do not know how they would do on a m.b..My advise,I would attempt to use a tire liner on a thorn resistant tube.I even contemplated on Instead of using commercial hard plastic tire liners to try metal or aluminum strip sanded and deburred to keep from cutting the Innertube and use It as a liner.And In my opinion.Tires could be made a lot better than they are Even air filled. but If they made them better.That would take the bottom dollar and supply and demand out of replacement parts and innertubes.Which Is a billion dollar business for bicycle companies and shops.Everything today Is created to malfunction In a few years or month's time so you either have to replace It or pay to fix It.

Glad to see someone besides me who thinks 40 mph Is not too fast.

I bet that these would slip too much on the rim, and who knows how well they would corner at speed.
